Gro-CART.

Specification of Lettei'sPatent.'

Patented Aug. 3, 1909.

Application filed. May 11, 1908. Serial No. 432,125.

Be it known that l, HARRY G. TRAVER, a citizen of the United States of America, and a resident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Gro-Carts, of which the following is a specification.

This invention relates to those baby gocarts which can be folded or collapsed and rendered portable for convenience in traveling on cars with the baby, and it consists `in providing a go-cart whichwill not only be much lighter, and cheaper to make, butwill also aord a stationary chair, a rocker, a swing, and many `other features for the greater safety, and contentment of the baby, as well as the greater convenience and satis.- faction for the parents in carrying the cart and the child about from place to place, and particularly in traveling on railroad or other conveyances.

Tothis end my invention consists in the,

peculiar features and combinations of parts more fully described hereinafter and pointed out in the claims.

invention, with the. manipulating handle raised as in wheeling position; Fig. 2, a front perspective view, showing the handle lowered as when the cart is converted into a stationary chair and the wheels folded back and raised clear of the ground; Fig. 3, a vertical section through the cart, as-.when it is folded up and out of use; Fig. 4, a rear perspective, as when the rear legs are lowered and the chair converted into a rocker. Fig. 5 is a horizontal section through the top bar of the inclined mainframe showing the handle locking device; Fig. 6, a transverse section through the handle connection in the `preceding figure; Fig. 7, a top detail view of the segmental gears which actuate the folding wheels; and Fig. 8 shows my device converted into a swing.

rlhe numeral 1 represents a rectangular inclined main-frame of the cart, and to which is hinged a pair of small wire wheels 2, revolving on the inturned axles 21 of a pair of resilient supporting frames or springs 3, each of which is composed preferably of a single' axis of the gears, and thence downwardly and laterally, finally terminating in the inwardly projecting axles 211 carrying the wheels. The segmental gears 4 encircle and rev'olveon the side bars of the rectangular inclined main-frame l. rlhe lower ends of the side-bars of the inclined frame 1 rest yupon the ground when the cart is standing.

The wheel-springs 3y are long enough to permit themito be swungforfolded around so as tolie substantially'in the plane of the inclined frame 1, as seen in Fig. 3, and these springs 3 are scroll-shaped to render them more resilient for the comfort of the occupant of the cart.`

, Theseat-frame is also made of heavy,

strong, roundw'ireand is rectangular in general outline7 .comprising a substantially U- shaped portion 8 forming the two sides and rear, together with a front horizontal rod 9. yThe vforward ends of the U-shaped portion pass through and are fixed in side-lugs 15 on the side of segmental gears or quadrants 10 fixed to the outer endsl of the front rod 9,

Awhichv rod passes through the side-bars of.

the main-frame. The beveledquadrants 10 mesh withfthe beveled segmental gears 4 encirclingy the side-bars of the main-frame. These beveled gears are supported on said bars by pins 12. From` the foregoing construction it will be seen `that when the rear end of the seat-frame is'lowered from an upright folded position, as in Fig. 3, to a su stantially horizontal position, the quadrants 10 will swing outward in the arc of a circle, thereby giving the gears 4 a quarter revolution on the side-bars, and swinging the wheel frames around in the operative position shown in Fig. 1. The sides of theU-shaped frame 8 rest upon the tops of the wheels rings 3 where they are held by hooks 20 on t e seat-frame, the weight of the child holding them together.

The cartpis held in a standing osition by resting the lower ends of the inc ined mainframe on the ground to support the front portion, and by sliding extensible legsat the rear. The rear legs are each-composed principally of two leg-sections 30 and 31, whereby they may be drawn up clear of the ground in it.

rlhe upper leg-sections 30 are composed of round wooden bars hinged to the upper inside of the main-frame at a point lying just below the hollow top-bar 33 thereof.

The lower leg-sections 31 consist of a continuous rod ot spring-wire having the general outlines of an inverted U. T he two legs 31 formed out of this wire pass up througl longitudinal holes in the wooden sections 30 each wire leg entering the hole at the bottom, and extending upwardly to a point near the top where they pass out laterally through a funnel-like opening 34, and thence out across to the outer sides of the handles 32 to which they are pivotally attached. The wire legsections 3l are connected at the bottoni by a horizontal foot 35, adapted to rest upon the ground when in stationary adjustment. The lowering of the handles will push and extend the wire leg-sections 3 l downward to lengthen the legs, as seen in Figs. 2 and 4. In this operation the second notch 45a in sleeve 42 will engage hooks 40 of the spring 36 and hold the handle in closed adjustment.

VTo hold the handles in raised position I provide a locking device which may be described as follows: As already stated the upper cross-bar 33 of the main-frame consists of a hollow member in which is placed a long bow-shaped spring 36 having a loop 37 at the middle which projects through a hole 39 in the bar, and serves as a push-button for thc hand in releasing the parts. The branching arms of the spring bear on fulcruins 38 located within the bar, and when pressure is exerted on the loop 37, it litts up the hooks 40 on the outer ends of said arms and releases the handle so that the latter will turn on the cross-bar 33. These hooks 40 lie in slots 41 in the under side of the hollow crossbar and snap into registering slots 46 in sleeves 42 embracing the bar, and to which the handles are secured, thus automatically locking the parts together, as seen in Fig. (i, whenever the handles are raised for wheeling the cart. For greater comfort in using the handles they are provided with pistol grips 49.

To convert the cart into a rocking chair, l have provided a pair of rockers 47, made removable by driving a heavy spring wire 43 in each rocker. The two upper free ends 43L and 44 are bent forward and sharpened to enter corresponding ioles in the back oi'' the lower part of each side bar, as seen more clearly in Fig. 4.

The foot 35 of the leg-sections 31 is attached to the rochers by means of a heavy wire staple 45 in the rear of the rocker, which staple has a substantially S-shaped top, under which the foot 35 is slipped and held down tightly to the top of the rocher in such a way as to prevent lateral or side movement. These two rocher fastenings are placed far enough apart to require springing the legs into iixed position. The folding scat-frame is provided with a leather bott om 5l stretcl'led over it. The lower portion ol' the cart is covered at the front and sides wit h a leather guard 52 fastened to the wooden si(le-.iars in any suitable manner. The rear edges of the lower halt of the leather guard "2 are loosely attached through the medium of a series ol holes 53 having eyelets .34, so that when the wire leg-sections are drawn up, the leather will crease or lold. l"o provide a swing for the child, suspension ropes 55 are attached by hooks 5G adapted to he applied to the cross-bar 33.

A back is provided for the inlant by stretching any suitable web 57 between the two upper leg-sections 30, and for still greater convenience this web is provided at the back with a large pocket 3Q in which various articles can he stored to relieve the hands of those who are propelling or carrying the cart.

lt will lie seen that the inclined mainframe, together with the extensible legs, constitute a framework which when open has the general outline el the letter A.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent, is:

1. .ln a combined eje-cart and chair, the

combination with a l'ranic having` the usual front legs, and being provided with a folding seat and folding wheels, ol' sliding extensible. rear legs, and a propelling` handle connected thereto and ada ited to raise and lower the legs.

2. A con'ibined go-cart and chair provided withfront and rear .legs and a traine having folding wheels, in combination with a handle connected to the rear legs and trame, and means between the handle and legs, whereby the wheels are thrown out ot action when the legs are thrown into action.

3. A folding go-cart having extensible legs and a folding handle which when closed lengthens the rear legs, in combination with an inclined frame with a cross-har at its top and carrying a seat and wheels, and means for locking the latter in open adjustment,

whereby the cart can lic carried without removing the occupant.

4. A folding `ro-cart provided with legs held out ol" action when the cart is in wheeling adjustment, in combination with a l'olding handle which extends the legs beyond the level of the wheels oi the cart to litt the wheels clear ot the ground, and to convert the cart into a stationary chair, and whereby l vl l) the vehicle can he carried about without removing its occupant, as described.

5. A go-cart having a folding handle hinged to a hollow liar containing a springlocking device.

A go-cart having extensible legs, in combination with a guard covering its lower portion at the front and sides `end loosely connected to the rear legs whereby the guard Will fold When the legs are shortened.

7. A go-cert provided with Wheels mounted upon the free ends of spring-frames, in combination With 2LV seat adapted to rest upon said frames, and Ineens for folding the Wheels and frames When the seat is liftedV and folded up into closed position.

8. A go-cart having e substantially A- shaped frame, in combination with folding eXtensible legs, and removable rockers to Which the legs and frame are secured.
